4-Chloro-3-(pyridin-2-yl)aniline → HCID 58614928, compound

Participants

Reaction Steps

1 g of methyl 4-((2-hydroxypropylthio)methyl)benzoate was oxidized with 2 g of MCPBA in DCM at −78° C. to form crude methyl 4-((2-hydroxypropylsulfonyl)methyl)benzoate. The reaction was evaporated and purified by ISCO Combi-Flash to yield 567 mg of pure methyl 4-((2-hydroxypropylsulfonyl)methyl)benzoate which was subsequently hydrolyzed via Procedure M to give 328 mg of 4-((2-hydroxypropylsulfonyl)methyl)benzoic acid. 50 mg of 4-chloro-3-(pyridin-2-yl)aniline was coupled to 4-((2-hydroxypropylsulfonyl)methyl)benzoic acid via Procedure G. The crude product was purified on reverse phase HPLC to yield N-(4-chloro-3-(pyridin-2-yl)phenyl)-4-((2-hydroxypropylsulfonyl)methyl)benzamide. MS (Q1) 445.3 (M)+.
